Estimate of shark ownership in US 12/3/08
Hi,? I am
writing an article for a veterinary journal regarding the medical care
of small sharks in the home aquaria.?? I am able to get figures from the
AVMA regarding the numbers of fish owners, but I was wondering if you
have an idea as to the percentage of fish owners who also own sharks?
Thank you,
Sharmie Johnson, DVM
<Mmm, there are no hard/fast data
re... but can give a qualitative guess based on figures for how many
Selachians of small species are imported through the major wholesalers
in the U.S.... and some sort of further guess-timate re how many of
these animals are alive after a given period of time. My best guess is
the numbers are in the low thousands... including small individuals of
larger species (e.g. the blacktip, Carcharhinus melanopterus, the Nurse,
Ginglymostoma cirratum) and coldwater species... the most popular being
Heterodontus francisci... collected along the two Californias mostly.
The remaining species that are more appropriate for home aquarist
keeping are principally Epaulette and Bamboo shark species, with a
smaller percentage of some Catsharks... After chatting with
Elasmobranch studying friends, and authors of popular shark writing, I
have mild confidence that most individuals kept last something less than
three months of capture/purchase... The percentage of marine aquarium
keepers of
sharks I'd put at 0.1 percent... about one out of a
thousand. Bob Fenner> Re: estimate of shark
ownership in US 12/16/08
Hi Bob,
<Sharmie>
Thank you
for getting back to me regarding the estimated number of sharks in
private hands.? Would it be okay if I quote you in my article as a "pers
comm?"
Thanks,

scyllium, shark sel. 11/20/2008
Hello Crew! I saw a very small pair of Triakis scyllium at a LFS. I
couldn't find any info on them. I was wondering what you knew?
<Have
seen this species intermittently offered in the trade...>
I am
guessing they are pretty much like a smoothhound shark. I would like to
get them but want to research first. My current tank is a 220 that is 6
foot long, 30 inches wide and 24 tall.
<Mmm, too small>
I run a
Deltec Ap851 skimmer, 300 gallon wet/dry,
<Inappropriate for shark
systems>
3/4 HP chiller (keeps my temp at 70), 36 watt Coralife UV
and a barracuda pump as a return. Water params are PH-8.4, Nitrite-0,
Nitrate-40, Ammonia-0, Sal 1.023. Tank has a 5" Lunare wrasse, 5" Naso
tang, 5" Yellow tang, 6 "Hippo tang, smaller hermits and a conch.
<All food>
40 LBS of LR stacked onto left side of tank to optimize
swimming room (rock wall like and stable). Overflow is on the outside as
well and tank has 150-200 LBS of very fine almost oolite sand. I have
kept sharks before and have a lot of experience with them I just cleared
my tank out and am waiting for a Port Jackson. However I want info on
the Triakis scyllium. I know they will outgrow this tank and I am in the
process of paying for a larger tank since I plan on keeping all my fish
for their full life terms.
Please let me know what you know. Thanks,
Andre
<This fish/species grows to about this systems length, is
subtropical... I would not try them here. Bob Fenner>
Shark Compatibility 011/04/08
Would an epaulette shark
be compatible with a couple of California Horn Sharks? I have never read
about any incompatibilities, but thought I'd check with you guys. I have
a 480gal tank, dimensions are 8' long, 2' deep, and 4' front-to-back. I
use oolitic sand, because it's the smallest grain available and I know
shark bellies are sensitive. The water is chilled to 72 degrees with a 1
hp chiller (necessary because I live in West Texas).
<Yes, the
California Horn Shark Heterodontus francisci is a subtropical to
temperate species. Slightly lower temperatures 65-70 F (18-21°C) would
even be better in the long run, especially when the animals grow. Also
see http://www.wetwebmedia.com/heterodontusfaqs.htm and the linked
articles.>
I have a minimum of rock work, and what I do have is
somewhat centered in the middle of the tank, so that the sharks can make
a full circle even on the bottom. My male Horn is 25" long and I've had
him over a year now. The female is about 15" and I've had her about 5
months. I've been very careful in choosing my tankmates so far...mostly
tangs, eels, and some bar gobies.
<Hopefully no tropical tankmates.>
No angels, triggers, puffers as I know they have a tendency to nip at
sharks.
Would a 7"-10" epaulette be OK or do you think I should pass
on it?
<The problem here is that one species (California Horn Sharks)
comes from subtropical waters while the other one (Epaulette shark
Hemiscyllium ocellatum) comes from the tropical waters (74-80 F,
23-27°C) of Northern Australia and New Guinea. Therefore, they need
different temperatures and should not be kept in the same system. Too
low or too high temperatures will likely result in a declining immune
system and shortened life span. Enforcing a compromise with intermediate
temperatures will make none of them happy or keep them healthy long
term.>
Thanks in advance. Robert.

Shark Species Advice - 8-13-08
Hello-
<Lovely morning? Mike
here today>
I maintain a 5600 gallon saltwater aquarium that is
cylindrical in shape (9' in diameter and 6' in height) with an
artificial reef in the center.
<Nice - I want one!>
The salinity
is 30ppt and the temperature is a constant 75°F. In addition, I have UV
sterilizers, a protein fractionator, fluid sand filters, sump with
heater, a chiller, and a huge generator. The system has been circulating
for 1 year and currently houses 2 gray triggerfish, 2 mangrove snapper,
2 jack crevalle, 1 Atlantic spade fish, and 3 grunts; all of which are
12+ inches except the grunts which are 6 inches. I wish to add a shark
(preferably, one native to the waters of the Gulf of Mexico) and
respectfully request your suggestion. Although my degree is in marine
biology and I have an experienced aquarist on hand, my concern lies with
the shark and maintaining a healthy environment for it.
I look
forward to your reply.
<Well, unlike most who wish to house a shark
in the home aquarium, you're well equipped to do so - that is a very
nice potential shark setup. Due to the volume and size, there are a
handful species available for you to (potentially) house successfully.
Are you looking for a benthic shark or a more active shark? See here for
an overview of possibilities: http://www.wetwebmedia.com/sharks.htm.
With the temperature of your aquarium, you're going to need a tropical
shark, and even with a large aquarium like you have, you're probably
still better off with a benthic shark. Have a look at the bamboo sharks,
the epaulette sharks, and swell sharks and see if anything catches your
eye. A perusal of our database will tell you all you need to know
regarding husbandry>
Thank you,
<Anytime>

Peppered catshark, sel. 7/26/08
I was
wondering if you knew any thing about the peppered catshark "Galeus
piperatus". I know there only suppose to get about a foot which would
make it ideal for the home aquarists. However I can't find anyone that
sells them.
<Mmm, have never seen this fish in the trade... according
to fishbase:
http://fishbase.org/Summary/speciesSummary.php?ID=810&genusname=Galeus&speciesname=piperatus
it's found in the upper Sea of Cortez... one can collect from this area
now-a-years, but... don't know anyone who does. Bob Fenner>
Clown Behavior, Shark Keeping, 6/26/08
Hello, I have a couple
of questions to ask.
<Ok>
First, a purchased 2 Clarkii
Clownfish about 2 weeks ago and ever since I put them in my 120
gallon tank, they have gotten along without any problems. One is
larger, about 2.5 inches, and one is smaller about 1.5 inches. Just
a few days ago I purchased a Bulb Anemone and ever since, the larger
clown fish has literally taken the anemone for himself. Now the two
clownfish fight over the anemone (obviously the bigger one wins),
and the smaller clown fish is left to himself while the bigger clown
fish lives in the anemone. Is this normal?
<Can be, it may
straighten itself out over time, although if this pairing does not
work out the fish may need to be separated.>
I'm afraid the
smaller clown fish will wade away over time without his partner.
<If the larger fish does not except the smaller over time then it
may cause problems, but clowns do fine solo, so a lack of a mate
would not cause its demise.>
Secondly, I was thinking about
upgrading to a large tank to house sharks. Either Smoothhounds,
leopards, bonnet heads, or possibly black or white tip reef sharks.
<Big, expensive, custom made tank then.>
I have been getting
mixed messages reading all the information on shark tanks and
wondered how big of a tank, and for how long I could keep each shark
until they outgrew the tank.
<Would need a tank of a few thousand
gallons, of a circular design, to keep these types of sharks for any
length of time. I feel that these are not appropriate of 99% of
fishkeepers, they are just too demanding.>
I know Smoothhounds
and leopards are cold water sharks, and the reef sharks and bonnet
heads are tropical. I purchased the Aquarium Sharks and Rays to help
me with my choice but in some ways the book complicated the whole
matter.
<Good book.>
Keeping the Smoothhounds would be
reasonable, but if I kept juvenile reef sharks, or bonnet heads what
size tank would I be able to get away with, and for how long could I
keep them until I give them to my local public aquarium (they
already agreed to keep my sharks once they got too big).
<I would
get this in writing, especially with the way the economy is going
and the inevitable shrinkage of their budgets as less public and
private money becomes available.>
Thanks,
Justin M.
<Welcome>
<Chris>
Re: Reef Shark Advice, sel. 6/26/08
Chris,
<Hello>
I have just read a response to a question asked by Justin M about
tank size for Bonnethead, black tip and white tip reef sharks. While
you may have been trying to help, I have to totally disagree with
your advice.
<Ok>
There are few private hobbyists that are
capable of housing bonnets and really none capable of keeping white
tip reef sharks for any length of time.
<Actually I think we are
in agreement here.>
It would take a tank of tens of thousands of
gallons or more to properly house the smallest of black tip reef
shark and much, much larger for white tips. It is most unfortunate
that anybody can get a hold of these sharks but it is made worst
when advice such as yours is given that as long as he gets a written
promise from the public aquarium, he could get the sharks.
<That
is not what I intended to get across, and stated earlier in the
query that 99% of hobbyist should not attempt to keep them.>
While you may not have directly stated such it is easily inferred
from your comments.
<I think you misinterpreted what I was trying
to get across, hopefully the writer did not as well.>
I was a
biologist at a public aquarium for a number of years and I can
assure you that most do not accept sharks from private individuals.
<Agreed>
I would respectfully request that in the future you
perhaps provide better worded and researched advice before making a
few off handed comments.
Matthew Hall
<I think you
misinterpreted what I was trying to say there, and if you look over
the WWM queries I think that you will find I have the same stance as
you do. No hobbyist except for the most wealthy among us who can
afford swimming pool sized tanks and exceedingly expensive equipment
should attempt to keep these fish.>

New question about an old issue, shark hlth., sys.
4/26/08
Crew,
<Tom>
Perhaps you remember (and perhaps you
don't) me writing a ton about a pet Banded Cat Shark that I owned, my
display tank having ick with the shark, and my treating the tank with
Quinine Sulfate in an attempt to eradicate the ick with the shark
present. And you might remember how the Quinine was very effective in
ridding the tank of the ick, but that the shark began a steady decline
over the course of a month and a half and finally passing away after
being unable to eat (this after feeding wonderfully on shark formula and
vitamins for 6 months, and doing quite well.)
<I do recall>
Months
have passed, and though I have added a few additions to the tank, we
have been nearly 4 months with absolutely no issues. But, my mind still
wanders back to that time and while I have no intentions or desire to
have another shark, I still think about what caused his demise.
I
don't really run carbon continuously in my tank. It's 200 gallons with
probably 150lb of live rock, filtered by a Fluval FX5 (which I clean and
rinse sponges every two weeks) used mainly for water flow and biological
filtration, a wet/dry trickle filter, and a large hang on protein
skimmer which is actually rated for 180 gallons. I do a 25% water change
every two weeks. But I do have a small canister filter that I put carbon
in and run on occasion. Obviously during the treatment with the Quinine,
I did not run the skimmer or the carbon. but after the treatment
duration I did appropriate water changes, turned on the skimmer and put
carbon back on the tank. Now, I wonder, how long is fresh carbon
actually viable?
<Mostly gets "used up" within minutes, hours...
rapidly drops off past then>
Some information outlets say change it
every couple of weeks. but some say the most effective use of new carbon
is in the first couple of days. being that this canister filter isn't
large to begin with, do you think that it was not effective at removing
all of this quinine, and the lingering presence of this medicine caused
the shark's demise?
<I do not>
Water parameters were the same then
as now, salinity was 1.025, PH was 8.2, 0ppm of both ammonia and
nitrites, nitrates less than 10 - 20 ppm at all times. Again, no
problems to resolve now, but something that bugs me and as I think about
it often, I might have new questions about it.
The tank now houses a
5" Passer angel, a 6" Lunare wrasse, a 5" yellow tang, a Maroon Clown,
and a Snowflake Moray. All have been problem free nearly all of 2008.
Thanks so much.

shark selection -04/11/08
hello.
i am currently thinking
about getting a shark. i have decided on 3 different sharks. then
white spotted bamboo, gray bamboo, and my fave. the swell shark. so
my question is what size tank will the swell shark need? i would be
getting a 240 most likely. would that be able to home a swell shark?
i have read that is enough for a white and gray bamboo. thanks for
your help!
<240g is probably the bare minimum. There's lots of

Swell Shark Home 4/12/08
Hey just wondering which size will
best suit a swell shark.
60x36x25 240g
72x30x25 240g
48x48x25 240g
280 - Wide
72 x 36 x 25 Tall
300 Wide
96 x
30 x 25 Tall
Obviously I wanna save money to the 240s are cheaper
but when talking for the shark should I just go with the 280/300 ? I
want him to be happy.
<None of these tanks are big enough for a
swell shark (Cephaloscyllium ventriosum), which reaches 3 feet in
length. To be honest, if cost is a consideration you should skip
owning a shark.>

<A 240
would work for a while, but not even close to the entire lifespan of
this shark, and good luck getting rid of an 18 inch shark when it
needs a good home. I believe this is what Sara was trying to say
when she said bare minimum.>
Also I had a list of different
dimensions that I was wondering which ones would be best. which I
have posted below thanks.
60x36x25 240g
72x30x25 240g
48x48x25 240g
72x36x25 280g
96x36x25 300g
I obviously want
to save money yet I want my shark to be happy so which would be
best?
<The shark may survive in any of these for a while but not
thrive. That’s all a bare minimum system will allow it to do. Also
sharks are very expensive to keep, it the price difference between a
240 and 300 is enough to make a difference you should probably try
keeping less demanding animals.>

Shark pond... sys., and stock sel., reading – 10/30/2007
Hello,
<Hi there>
Long time reader, 1st time I've written. Thanks
in advance for your time / advice.
<Welcome>
I've argued,
reasoned and walked away from people who wanted me to help them setup a
200 gallon shark tank, but for the first time have a customer that
presents a possibility that just might work. I have a great deal of reef
and FOWLR experience but I've never owned, sold, or cared for a shark.
The pond was to have been for Koi, now he is thinking saltwater and
sharks / rays. The system will be just under 1600 gallons, 24 ft long,
3.5 ft wide and 2.5 ft deep. It is best described as a cement "tray"
which will be tiled on the sides and have a substrate of our choosing on
the bottom.
This "pond" will be indoors, we could include a very
large chiller, but I would rather stick with animals that will do well
in the area of 75 degrees.
<There are many>
Filtration will be a
skimmer, something big, though we will have some kind of height limit.
Something like this:
http://www.championlighting.com/product.php?productid=21017
<http://www.championlighting.com/product.php?productid=21017&cat=646&pag
e=1> &cat=646&page=1 or bigger / better if possible.
<Okay... though
I would write RK2, EuroReef... look into something "larger" in terms of
function here>
Everything I read simply suggests a "large" tank and
at least 3 * the animals length. I would like to keep everyone as small
as possible.
Under 30, maybe 36 inches have a bit of variety in the
animals and stick with hardy, easy inhabitants. I am worried about the
width of the pond and larger fish being able to make the turn.
What
combo of sharks, rays, eels and anything else would you suggest?

Brown Banded Bamboo Shark Adoption 7/17/07
Dear WWM Crew,
<Hello>
I have had a brown banded bamboo shark for about 2 years now
(hatched him myself). He is at, about 15 inches and is in a 125 gallon
tank. A couple weeks ago he stopped eating but I emailed you guys and
after changing his diet and lowering the nitrates, I got him to eat
again. <Good> I have an empty 75 gallon tank that I'm going to turn into
a reef tank but I cannot afford to have two tanks running at the same
time so I was going to sell my 125 and bring most of my fish back where
I bought them, but I would not like to do that with my shark unless I
have no other options. <If they will take it most likely your only
option.> I think I read somewhere on your web sight that you are a
public aquarium and I was wondering if I could donate my shark to it.
<Unfortunately not, Bob is working on something in Hawaii, but it is
just in its preliminary stages.> I live in Florida but could find a way
to get it to San Francisco (correct me if that's not the right place).
Please email me back when you get the chance.

Coral Catshark and Soapfish 6/24/07
Hi again Crew!
<Katie>
I have been hearing some mixed information when it comes to
this topic.
Recently I purchased a sixline Soapfish, a fish I have
loved for a long time. I was aware that they produced a toxin in their
mucus coating but I was under the impression that it was a defense
mechanism, so of like with cowfish. How risky is it to keep these guys
with other tankmates?
<Mmm, not much... in a "large-enough",
well-maintained system, minimal>
Is it fairly rare to have them kill
a tank full?
<Yes... would have to be small, die, dissolve unseen...>
He is currently in a 55 gallon but will make a move to a 150 gallon
within the next month or so.
<Good>
Also, I plan on keeping a
coral CatShark in the 150 gallon (until it outgrows it). I have heard
that coral catsharks mainly eat crustaceans and will not bother most
fish, but I have also been reading lately that its not uncommon for them
to attack tankmates while feeding....?
<Mmm, yes, at feeding times
at times... or most anything... bite rocks, what have you in a sort of
"frenzy">
Does this mean its probably not wise to keep a coral
catshark and a sixline Soapfish in the same tank, because of the toxins
in the soapfish's skin?
Thanks in advance for the help!
-Katie
<Not likely... most Grammistids are rather shy, secretive... and seem to
be aware of such predation. I give you good odds of not having problems
here... and if the G. sexlineatus should be consumed in this 150, I
doubt if this would created a toxic situation. Bob Fenner>
Public Aquarium Fish, Collecting, moving sharks, rays
5/30/07
I am currently building a public aquarium in Chiang Mai,
<Oh! Was just (back) there a few months ago... Has this town grown!>
Thailand with a main salt water tank of 4,000 cubic meters. Do you know
of any reliable, humane and responsible suppliers of sharks and rays
which it is intended to display here.
<Mmm, quite a few... I would
contact the Director and Curator at the new Bangkok Aquarium for their
help here>
The aquarium is part of Chiang Mai zoo and I am afraid
that it may end up in a call going out to local fishermen to supply part
of their catch.
<Mmm... it is NOT easy to transport cartilaginous
fishes caught this way generally... I would also contact the folks at
Monterey Bay Aquarium for help here re techniques, gear...>
Although
they can catch them they cannot transport them nor be guaranteed to
behave in a responsible manner.
<Bingo... YOU need to have a boat
near, or catch these fishes yourself... WITH the tank, pumps for
recirculating water through the fishes mouths... likely anesthetic
(MS-222...)... and a ready-to-go live-hauling truck to move all to your
town... stat!>
Unfortunately, I know a lot about acrylic, life
support systems and theming but not much about fish (at least
commercially).

experience, or travel, send someone to visit other institutions re these
areas of expertise. Bob Fenner> Overseas Purchasing of
Marine Sharks 4/3/07
Hello all and thank you in
advance. I have a 18,000 gallon shark pool and am considering
purchasing some black tip reef sharks from an overseas supplier. I am
writing to inquire if this would be wise for an individual to do. Is
there any type of directory or method to verify the legitimacy of
wholesale suppliers out side of the US?
<Unfortunately no... there
is not such a list of "legitimate players"... and/or not... And indeed
there are outright crooks in our trade... Internationally, including
within the U.S.... FWIW (which is a great deal here), I STRONGLY
encourage you to deal with/through a U.S. based wholesaler... Likely
Quality Marine or Sea Dwelling Creatures, Underwater World on the west
coast... Or All Seas in L.A. or Miami... Perhaps best done with the
cooperation of a LFS you're friendly with... for a nominal pass-through
fee... Your "net landed cost" for these Carcharhinids will very likely
be less... perhaps very much so... due to the economies of scale of
shipping, CITEs, Customs, moving boxes about... There is much we might
discuss here... but suffice it for here/now, that I encourage you to ask
you local fish store re this possibility, and have them in turn contact
one of the "A" players listed above. All will have to be arranged to
have you notified re their ETA, close pick-up, processing locally. Bob

<<Honestly Eddie, I don't think pursuing this
shark for aquarium keeping is a practical exercise. These sharks are
bottom dwellers found only in very deep waters (more than 600
feet)...couple this with their small size and low fecundity it's likely
they don't often show up as by-catch by the commercial fisheries, and
almost certainly never as "aquarium" specimens...and as such, any
information on husbandry will be non-existent. Regards, EricR>>

CA leopard sharks 1/5/07
Mr. Fenner,
I'm
not sure how often you are asked about Leopard sharks,
<Too often my
friend... almost never are these animals kept in appropriate
circumstances by hobbyists>
or the areas your readers frequent, but
someone had forwarded me a link to your page, and I saw a few articles
about leopard sharks. I'd be happy to answer any questions regarding
the legality of different things kept as pets in California.
<Would
you mind us... am inferring this here... positing your email address?>
Specifically, fish that are native to California, although I could
attempt to help if there was a question about exotics, as we do restrict
some species.
<Thank you>
I do not want my email address made
public/posted, however you may contact me if you have any questions.
<.... what? By smoke signals?>
Leopard sharks must be 36 inches in
total length to possess in California, regardless of their source.
<Wow, I was unaware of this... is this a new advent? The trade sells
these at much smaller sizes... perhaps they're originating outside the
State>>
The only exception is if someone can show that they have had
it as a pet since 1994, and received written permission from the
Department to keep it. Thank you, LT
Hartman
<Again, thank you
for this input. If there is a further referent, some place to send folks
to re... Please send this address, URL along. Bob Fenner> Re:
CA leopard sharks 1/5/07
Mr Fenner,
If
persons have questions or want more information they can go to the
Department's website at www.dfg.ca.gov
Most of the information they
would be seeking would be under the Marine Resources area.
<Thank
you for this>
They can also email the Department at
askmarine@dfg.ca.gov Feel free to make that email address available to
your readers.
<Will do so>
As for the regulations on leopard
sharks, the size limit was established in 1994/95. The illegal trade of
undersize leopard sharks is a Black market of sorts,
<Ahhh! As you
will realize, I am not a fan of keeping Triakis, most any other
Selachians in home-size systems... They don't live in such very long or
well>
and resulted in numerous arrests last year by the Department
of Fish and Game and NOAA. There is no exception to the size limit,
even if the sharks are brought in from Mexico of Portland.
<Really?
Good to know>
Possession of a leopard shark under 36 inches in
California is a Misdemeanor, punishable by a fine of $1,000 and or 6
months in jail. The section is Fish and Game Code 8388.5, available on
our website. Hopefully this will help keep some of them out of those
little tanks. Thanks, and feel free to contact me our

Bob,
I am going to be having
a custom 325 gallon aquarium built. It is going to be a flat back
hexagon shape with the dimensions 84"x24"x10"x64" at a 30" height.
Besides the Brown Banded Bamboo shark are there any other species that
tend to be more active

I could house in this size tank ?
Thanks,

sys. 11/14/06
Hey Bob,
I am located in Toronto,
Canada and was browsing your website and was fascinated by all the
useful information I found. For the past 1 and a half months I have been
doing a lot of research on the Brown Banded Bamboo sharks. I have read
and gone threw
<through>
multiple websites, joined multiple
forums, and bought many books including Scott Michaels " Aquarium Sharks
and Rays" which was very informative. I will be purchasing a 250-300
gallon aquarium soon which will be the home for 2 Brown Banded Bamboo
sharks. It will be a flat back hexagon shape with the dimensions
84x24x10x64 with a 30" height. Do these dimensions sound good for Brown
Banded Bamboo sharks?
<For a short while, for small specimens>
For feeding would you recommend live food?
<No... fresh/or defrosted
meaty foods>
Or frozen food. Most people I have talked to
recommended frozen would, on a feeding stick to ensure I give both an
equal share.
But some say its easier to get them acclimated with
live food?
<Unnecessary>
Is this correct or no? As well when I
first introduce them into the aquarium how do I go about acclimating
them?
<See WWM re... marine fishes period>
When I purchase them
they will either be in eggs still or newly hatched. Should I leave them
in the bags and place those bags in the aquarium like most fish are
acclimated. Or should I place them in bucket with the same water as in
the aquarium and then half of the water from the bag they came in?
<This latter>
Please let me know as I want to offer these sharks the
best living conditions I possible can, and want to make the transition
from the store to my aquarium as stress free as possible. I look forward
to hearing from you.

<Will need more room in time. Bob Fenner> Active Sharks for
a 1250? – 10/25/06
Greetings WWM crew.
<<Hello James>>
I'm having a custom made shark tank built for a client. The tank will
be oval, 8' long, 6' wide, and 3.5' high.
<<Neat!>>
My client
wants an active swimming shark, so bamboos are out.
<<Mmm, but
therein lies the problem. “Active” sharks require much more space/care
than this tank can provide; not for a mature animal...and your client
shouldn’t consider keeping anything that can’t be cared for long-term >>
I've been looking into spiny dogfish, smooth-hounds, and as of tonight
Bonnetheads, but I have a few questions that I haven't been able to find
answers to yet.
<<Temperate to sub-tropical sharks, will probably
require a chilled system...and even the smallest will likely grow to
about 4-feet>>
Firstly, which shark do you think would have the best
long-term success in this tank, and what numbers (single, pair, three)?
<<Um, not what you want to hear but...two, maybe three Bamboo or Coral
Catsharks>>
Lighting - I was thinking of three 150 watt metal halide
pendants. Do you think they would be a good choice, or too bright?
<<Should be fine if they can be raised as bit (will provide nice
“glimmer lines”) and rockscaping is such the sharks can reach/rest in
shadow if they wish>>
On a setup like this, are a UV sterilizer and
ozonizer necessary components, or a waste?
<<Both can be of benefit
if sized/utilized properly>>
Water flow - Being an oval tank, should
I try to create a circular current, or would sharks prefer a more reef
like/random water flow?
<<I think a “circular” current would work
well...especially if it can be periodically reduced/reversed (six-hour
durations)>>
I was planning on using either 3600 or 2500 GPH pumps
to create two closed-loop systems, and I can run them through a wave
maker if needed.
<<Sounds good...do have a look at “eductors” (
http://www.aquaticeco.com/index.cfm/fuseaction/listings.categories/ssid/460)
for multiplying/spreading flow>>
The tank will be filtered with a
very large wet/dry filter and protein skimmer.
<<Might I suggest a
large fluidized-bed filter in place of/in addition too the wet/dry as
these are able to react very quickly to shifting bio-loads associated
with these big, messy feeders>>
Lastly, (for now) I've read on here
several times about adding vitamins to their food, and have followed
links you've given to where the answers are supposed to be, but I have
yet to be able to find what kind of vitamins they should be given, or
the amount.

Re: Active Sharks for a 1250? – 10/30/06
Thanks for the reply
Eric.
<<Quite welcome James>>
I realize bamboos are the best
bet, but these (spiny dogfish, smooth-hound, and Bonnethead) are about
the best compromise I can come up with (unless you know of a <3' active
shark?) to prevent a Blacktip reef shark from going into the
tank. Other stores in town would gladly bring in a Blacktip just for
the profit.
<<Then educate your client otherwise. As important as
size is in this 8’ x 6’ oval display, the fact your client wants an
“active” shark compounds the problem. Active sharks require MUCH more
room than bottom-dwelling or “sedentary” sharks of the same size. I
just don’t feel this tank is large enough to house an “active” species,
and that doing so will only result in a greatly foreshortened lifespan>>
I'm hoping the shape and water flow will enable the shark to keep a
fairly normal swimming routine (would a stronger current help with
this?).
<<The oval shape is definitely a bonus, and water flow
should be about 2x the tank volume or so>>
I did read on your site
about a 15' cylinder tank with strong flow that had a Blacktip I
believe, that allowed it to swim fairly comfortably.
<<Mmm, but the
diameter of the cylinder is nearly twice the length of the long-side on
your system...big difference>>
It was also mentioned on here that
Bonnetheads often max out at around 3' in an aquarium, which will
hopefully be the case. I intend to try to get in a male to keep it even
smaller.
<<Though this species may well be the best choice of the
three mentioned, the issue here is the “activeness” of the shark in this
system. Even at three-feet, an active species is going to prove “too
big” I think>>
I've taken a look at the eductors, and will probably
try them out. I'll also look into a fluidized filter. Any
recommendations on manufacturers for them?
<<Hmm...finding one
“large enough” may prove difficult. Look at the Pentair Rainbow
Lifegard FB-900. The design of this filter should allow several to be
easily plumbed in tandem to create a filter large enough to support the
system>>
Another question I have is regarding substrate. I prefer
deep sand beds for my reef aquariums, but am unsure of which way to go
on a shark tank. Deep or shallow?
<<Many sharks are diggers, a
shallow substrate of crushed coral (1mm-3mm) may be better than a DSB in
the display. Perhaps you can locate a DSB of sugar-fine aragonite in a
separate vessel plumbed to the system?>>

Suitable Shark(s) for the Home Aquarium? 10/10/2006
Hello again.
I have been doing research on the Speckled Epaulette and the Freycinet's
Epaulette Sharks and have found that they reach a maximum length
slightly smaller than the other choices of sharks that I have questioned
(besides the catsharks). What size tank would you recommend for these
shark species and where could I buy them (if the right specimen for a
tank of this capacity)?
Many thanks,

Shark Tank...How Many? How Big? – 10/09/06
Eric,
<<Chad>>
What shark species could I keep in a 265 gallon tank? Possibly a few
Cat Shark species?
<<Mmm, not a “few” but possibly a single specimen
of one of the smaller species...and then probably not long-term. Atelomycterus
marmoratus, the Coral Cat Shark is likely your best option here (a
true tropical species), obtain as a juvenile or better yet as a
developing egg case>>
And also, what size tank could I keep an adult
Brownbanded Bamboo Shark or an adult Epaulette Shark?
<<Hmm...ideally, one in which the smallest dimension (length/width) is
at least three-times the adult length of the shark>>

<Possibly>
Also I have a titanium
ground probe to remove stray voltage from my aquarium but before I added
it on i tried it on a tank with no fish (the tank am cycling) and when i
touched the water it sort or gave me a little feeling of electricity!!
<What? I would have this water/system tested... Make sure all
electrified gear goes through a GFCI.

Is that supposed to
happen or am i not supposed to be able to feel it?

9/19/06
The Atlantic Sharpnose Shark (Rhizoprionodon
terraenovae) is my dream shark that I would like to keep - if I ever had
to money & space to do so).
<Here on fishbase:
http://fishbase.sinica.edu.tw/Summary/speciesSummary.php?ID=905&genusname=Rhizoprionodon&speciesname=terraenovae>
The Atlantic Sharpnose is a small coastal requiem shark, that is
native year round) to the southeastern (From the Carolinas to Florida) &
entire gulf coast of the U.S. And has been found in New England waters
during the summer months.
It also grows to between 3-4 ft. And is
a highly active species.
I've also heard that it adapts fairly
well to captivity (similar to a Blacktip reef) at least according to the
people I talked emailed) who have kept both sharks. They also say that
it's about as hardy as a Blacktip reef. A few keepers - even go as far
as to say that it's a better alternative to the Blacktip reef - due to
it's smaller adult size.
Any thoughts?
<Is better than C. melanopterus... though still has about the same
space, environmental needs>
While I done some research on this
shark - I still have a few questions.
Due to it
home range I would tend to classify it as a warm water shark. Because I
know from personal experience that this shark appears to very common off
the NC & SC coasts) From early May - mid September when the water temps
are between 75-84F.
So do you think that it fair to call it a warm
water shark, or that just wishful thinking on my part?
<I'd say
tropical to sub-tropical... can live in warm water for sure>
The
confusing part sort of), comes from when I was talking to an online
dealer who cares sharks) -just to inquire (no actual plans to buy) about
this shark. I emailed him, because I wanted to get a feel of this guy as
I was considering buying other more "aquarium friendly" sharks - like
catsharks, bamboos or horns.
Here's a few things
that he told me about the sharpnose.
- They required water temps
of less than 76F.
<Interesting. The water is assuredly warmer in
this fish's distribution range... though lower captive temperature is
advised certainly... to allow for enhanced gas solubility, depressed
metabolism>
- They are only as hardy as bonnetheads.
<Agreed>
- That they require a pool at least 16ft in diameter(4500-6000
gallons) - which I consider a good idea.
<Me too>
- They
should be watched daily - since they don't adapt to captivity well.
<Okay>
Also I got the feeling he was down playing the sharpnose,
because he wanted to sale me a couple of smooth hounds.
<Mmm,
doubtful... The industry is made up (as is the larger human population)
of makers, takers and fakers... these last two categories are not folks
who last long... I suspect this dealer is "the real thing"... a maker.
As am I>
Saying things like talking about the smooth hounds) -
-they are warm water sharks,
-require smaller tanks,
-and
get to be about the same size,
-and a hardier shark.
What's your thoughts on this.
<They are, I agree. Bob Fenner>
More on Sharks - 09/14/06
Hello Eric!
<<Hi Chad!>>
Chad
again asking a few questions for a friend (doesn't have internet).
<<Uh-huh (just kidding matey <grin>)>>
His name is Nathan, I just
recently got him interested in keeping one of the many beautiful
Elasmobranchs.
<<Indeed>>
I showed him pictures of the
Brownbanded Bamboo, Epaulette, Cat sharks, etc. But he saw a picture of
a Bonnethead and a Blacktip Reef Shark.
<<Uh-oh...(sigh)>>
He
wanted me to ask you guys if he could keep a Bonnethead or a Blacktip
Reef Shark in a 1000 - 1500 gallon system who's dimensions are 12ft L x
4ft W x 3ft H?
<<Mmm, no...These are heavier, more active and much
larger sharks...the Bonnethead grows to more than 5', and the Blacktip
to more than 7'...would need a tank more than twice this size for
either, in my opinion>>
I told him that he probably couldn't keep
them in there for more than about 8 - 12 months or so, but he wanted to
know exactly how long and he wanted to hear that from experts, so I
asked you guys.
<<Well...I'm hardly an expert, but I have been
around the block (or maybe around the bend!). I don't recommend keeping
these sharks at all unless they are "started" in a system suitable to
hold them at maturity. Often the "bigger tank down the line" never
materializes...and rarely if ever can you just "bag up" the shark and
take it to your local public aquarium or zoo, due either to local
protocol or just the fact that they can't handle/don't have the
facilities for the addition. There's also the matter of developmental
retardation from keeping and “growing” an animal under improper
conditions and/or in "too small" an environment. I can't point you to
any studies, but my colleagues and I deal with this on a daily
basis. Mostly in the form of health and behavior issues associated with
folks keeping "Tangs" in too small/crowded systems..."but only until
they get too big for the tank" or "only until they can get a bigger
tank"...get the picture? Few hobbyists have the money/time/capacity for
keeping these magnificent creatures...maybe you (and your friend) are
the exception, just be sure to match the species to the
environment...and vise versa>>

I just recently purchased Scott W. Michael's book on
"Aquarium Sharks and Rays" and it is great!
<<Indeed>>
I was
wondering what kind of shark I could keep in a 1,200 gallon aquarium
with rounded corners?
<<Well Chad, admittedly sharks are not my
forte, but even at 1,200 gallons you're still best off keeping the
smaller sharks commonly known as "Cat" sharks and "Bamboo" sharks. A
trio would make an interesting display here I think>>
I will look
forward to talking to you guys in the future.
Thank you very much,

<<Be chatting, EricR>> Re: Which Shark(s) for a 1,200

Thank you for the quick reply!
<<Quite welcome>>
I have read Scott's book up to "A Catalog of
Sharks and Rays" so far and it says that I could house a Brown
Smooth-hound Shark comfortably in a 1,200 gallon.
<<Mmm, possibly
yes. Attains a maximum length of about 45" which "might" be fine
depending on the dimensions of your system, but I also believe this is a
"cool water" species. Are you prepared to provide water cooling for
such a large system?>>
I am not trying to argue with you (please
don't think that!)
<<No worries mate...we encourage hobbyists to
research/think on their own>>
but the ONLY reason I do not want to
keep a Cat, Bamboo, or Epaulette shark is the fact that they lay or
"walk" on the substrate all day and I love to see them swimming around.
<<I see>>
I wish I didn't think so but I just cannot help it. But,
if I did get a Brown-banded Bamboo Shark, could I turn the light off
during the day and turn the light on at night so I could watch them swim
around, or would that be a bad thing to do?
<<Not "bad" at all. It
is quite OK to set the lighting schedule to suit you/your
schedule. Just be sure to put the lights on timers so a regular routine
is established>>
P.S. A trio would be awesome!!!
Thank you Eric,
Chad
<<Quite welcome my friend. Eric Russell>> Re: Which
Shark(s) for a 1,200 Gallon System? 9/11/06

the dimensions of the tank are going to be 12ft L x 4ft W x 2.5ft H. I
would be prepared to provide the proper needs for any shark that I
get!!!
<<Ah good...I think a few Cat, Bamboo, or Epaulette sharks
would all be fine inhabitants...or a single Brown Smooth-hound if you
decide. EricR>>
Thank you,
Chad Re: Which Shark(s) for a
1,200 Gallon System? - 09/12/06
Just one final question. How
much does a Brown-banded Bamboo Shark swim around at night? Just as
much as an active shark would during the day maybe?
<<Hmm, don't
rightly know...would think much of their "hunting" would be done at
night. Take a look here (http://whozoo.org/Anlife2001/callmatt/CMM_Bandedcatshark2_JES.html)

I was thinking maybe a Great White.....NOT REALLY!!!! Thought I would
try to be funny.
ANYWAY , I'm seriously thinking about a Brownbanded
Bamboo Shark or a Hooded Epaulette Shark. Would these sharks be able to
live there entire lives in this tank?
<Depends... on the shape of
the tank of this gallonage...>
Would you recommend me put a pair of

Hello, I visit your site from time to time but have
never posted. At the moment I am in Las Vegas for a business trip and
noticed that there was a Leopard shark swimming around in the big
tropical tank behind the check in desk at the Mirage hotel.
<Arrrrrgh....>
There were a bunch of tangs, puffers, the usual
tropical home aquarium fish. My question is, why would they have a cold
water specimen in warmer waters if the care takers are suppose to be
pro's at this?
<A very, very good question, my
friend.... and one to which I have no happy answer.> <<I do... Just as
you get "fair odds" in gambling there, this Triakis is getting "fair
odds" at living a long, healthy life. Id est, none. RMF>>
Is it
possible for the shark to be fine and not have a problem living like
this
<Not long-term.>
or will it die because of the conditions?
<Ultimately, yes. This animal, like all too many others, should be left
to the oceans and large public aquaria that can properly house them.>

<Of shark I would personally keep none…just because my personal belief
is that shark quarters should be pond size or they should be left in the
ocean, however there are a few which people commonly keep in tanks of
this size.>
If I did a shark, I would like it to be a brown banded
bamboo shark.
<Potential size of this animal is 40”+ so beware of
that….may/will outgrow quarters.>
And I would just have that one
shark with possibly one ray (my LFS suggested I put a shark with a ray
for the 220 gal.)
<No tank is too small.>
But I also like other
fish such as triggers,
<Not good to mix with sharks, will/can pick
on sharks.>
tangs, groupers, etc.
<This is okay…but a heavy
bio-load…messy, messy, messy.>
I know it to be wise not to keep fish
with sharks.
<Well benthic sharks like the bamboo are actually not
much of a threat to larger healthy fish, they couldn’t catch them if
they wanted too.>
So it's either one or the other: shark tank or
fish only tank with the fish only tank hosting a Clown Trigger, Picasso
Trigger, Blonde Naso Tang, Brown Powder Tang, Stars and stripes puffer,
ghost ribbon eel.
<I would say go for the fish only for the best
long-term display but pick one trigger or the other and drop the ribbon
eel from the list completely…these are to be left in the ocean….trust me
it WILL perish in captivity, especially with the aggressive tank-mates
you have mentioned.>
Of course not all of them but the choices I
would like to have. Anyway, what would be the best tank to have,
shark/ray tank or fish only tank?
<The fish only my friend, without
a doubt.>
Thanks
<Sure.>

<Bob
Fenner> Overseas Suppliers of Sharks 3/24/06
Hello all and thank you for taking time to help those who so need it. I
am in the process of acquiring marine sharks for my large (35000 gallon)
shark lagoon and was contacted by several overseas collectors. My
question is if there is any way to verify that these companies are
legitimate and if they have solid track records?
<Mmm,
only by referral really>
Even taking into account freight costs,
many times it is far more affordable to buy direct then from local
suppliers.
<Oh yes... do make your needs known of Public Aquariums
"within driving distance"... as they are offered such animals by
donation and enforcement agencies periodically... and don't have the
facilities to handle all>
Thank you again.

Fenner> Chained Dogfish (deep water chained "catshark")
3/24/06
Greetings, Wet Web Crew. First of all, thank you for
your prompt answer to a previous question that I had on shark egg
care. I am interested in acquiring a Chained Dogfish or an egg. I have
read that these are very hardy animals to keep, and that they stay
around a foot in length. I have also heard that the only disadvantage
is finding a captive source, because they are a deep-water Atlantic fish
that is rare in the aquarium business.
<I have never encountered
this species in the trade>
I am friends with the guys down at Wet
Pets, and we weren't able to find a source for these mislabeled
"dogfish". I did find one petting zoo / aquarium in Maine that had
several specimens on display, but they weren't sure where to acquire
more. I have experience with adult catsharks and coral sharks, and have
a sincere professional interest in the chained "dogfish". Any further
information whatsoever would be thoroughly appreciated. Thanks, crew.
-Peter Sewchok
<Mmm, you might try to follow-up with the Public
Aquarium... if they have theirs reproduce there may be a way to acquire
these. Bob Fenner> Cat Shark...Other Stocking Question -
03/16/06
Crew,
<<Eric>>
I appreciate your input.
<<My pleasure>>
I am going to leave the shark out of the mix.
<<You will both likely be happier for this.>>
It will get a little
too big for my tank I think.
<<Me too>>
Now I think I will plan
on a few tangs, a queen angel (my wife loves this fish), a couple of
pygmy angels, 5 to 7 green chromis, and a harlequin tusk. My new
question is on the harlequin tusk. I am not very familiar with this
fish and I have read differing opinions on compatibility, with some
material indicating the tusk will eat small fish and others saying it's
safe. Can green chromis and other small fish (clowns) be safely kept
with a tusk?
<<In my experience/estimation, yes.>>
Thanks
again!!!

Leopard shark... abandonment issues 03/07/06
I have
had a leopard shark in a 1500 gallon pond for about the last 3 years. I
am now forced to move back up north (I am in Florida now) due to my
parents becoming ill. I am not going to be able to get my pond set back
up soon enough to bring her with me. I was wondering if you knew the
contact info for sea world or any other aquarium that I could possibly
donate her to? This all came up very suddenly so I need to try to get
her placed as soon as possible. Thank you for any help

try contacting... Maybe Bruce Carlson at the new Atlanta Aquarium... but
not good odds. Bob Fenner>
Saltwater questions.. Shark sel.,
systems 3/4/06
Hi Bob,
<Joe>
I have a few
more queries which I'd like your help for.
<Will do my best>
Firstly, I have a chance to purchase a Colclough's Shark, and knowing
how rare these are, would like your opinion on whether these sharks
might live well in my tank.
<The genus does about as well as any
captive shark species. Have never seen this fish in the trade in the
U.S., but sometimes sold in areas closer to its Australian origin:
http://filaman.ifm-geomar.de/Summary/SpeciesSummary.php?id=5893>
My area of concern is the temperature range to which they are
accustomed. Scott Michael's book states this range as being between 18
and 24 degrees Celsius. We have just come out of Summer in Australia and
I have noted that the tank maintains an average temperature of about 28
-30 degrees Celsius.
<Mmm, yes... I would employ a chilling
mechanism here for sure>
While I am certain that this will drop a
few degrees during the winter, I do not want to purchase this shark only
to let it suffer next
summer. Do you think the shark will be
comfortable given this temperature?
<Not likely. We have a similar
"challenge" here in S. California with folks trying to keep Leopard
(Triakis semifasciata, now banned I'm given to understand), and our
local Port Jackson (Heterodontus francisci)... some success during the
winter months, almost none w/o chilled systems during the summer>
If
not, I would prefer getting an Epaulette which has a warmer range.
<A better choice w/o the chiller...>
Secondly, I am aware of a
certain product on the market ("Deniballs T by Aquamedic) which claim to
reduce nitrate by slowly dissolving over a period
of a year or so.
Is this product essential to a successful marine aquarium or is it
simply a money burner?
<Mmm... a worthwhile expedient for some...
Nitrates can be a "menace"... but given other means, not necessary. You
do want to keep these at a minimum in shark systems... less than 10
ppm.>
Are water changes enough to control nitrate?
<Well... not
unless you're super-wealthy, to afford bunches of salt mix, or have a
hose pipe from the sea to maintain an open system... Other means are
detailed on WWM... Should be reviewed>
Since I will be keeping a
shark and ray, among other fish, do they have a specific low-tolerance
to nitrate??
<Yes! Any is of trouble really...>
Finally, are
cooked shrimp better/worse than raw shrimp to feed to my fish?
(In
regards to nutrient value and disease carrying potential).
<Worse
nutritionally>
Thank you very much for your time and effort,
Joe
<Thank you for helping us all by asking, sharing. Bob Fenner>

Shark sel. and ray system 2/3/06
Hello, I have
done tons of research on sharks and from many websites, including yours,
the best shark for a smaller home aquarium, would probably be the
marbled cat shark or also known as Indonesian speckled carpet shark,
Hemiscylliidae freycineti, closely related to the Epaulette shark. This
shark, not the epaulette, reaches a maximum size of 28 inches, but some
sites say 22 to 24 is maximum. I have recently discovered another type
of shark that is not advertised for sale on the internet but was at my
LFS, it was the Gulf Cat shark, Asymbolus vicenti,
<You've
misspelled the name:
http://fishbase.org/Summary/speciesSummary.php?ID=789&genusname=Asymbolus&speciesname=vincenti>
maximum length at 23 inches. Do you have any info on this particular
species?
<Mmm, nope. Have never seen it in the trade or captivity>
Can I keep it with live rock or is the risk of infection to much. I
thought it should be ok do to its natural habitat is in rocky
areas. One more question, can I keep a blue spotted ribbon tail ray,
Taeniura lymna, in a tank that is 4 ft long, and 18 inches wide?
<... possibly. Though very few live in captivity in any size system for
long. Not a good gamble>
The only reason I ask this question which
may sound crazy is because some sites say a 75 is minimum,
<Get
longer than this sized box>
people I know say this would be a fine
size, and that my local fish store says that it will be ok. These rays
in particular mostly lay in the sand unless agitated or frightened, or
in times of feeding. I know they are not the hardiest and don't have
the greatest survival rate but in my experience, I have been told that
there was no way I could keep a blue ribbon eel or banded snake eel
alive, and that the minimum size tank for a banded snake eel was 180
gallons according to Scott Michael's book and I have been successfully
keeping both specimens in a 55 gallon tank for over 2 years. This makes
me question recommendations.
I know this is a lot to digest, just
looking for more info and input.
Thank you and your site for
continuous help,
Chris
<In good hands, care, animals can be kept in smaller confines... are
they happy, long-lived? Bob Fenner> Carcharhinids not in

Coral Catshark... selection, systems
1/17/06
Hello,
<Greetings>
I was interested in getting a
coral catshark, and was wondering if you could recommend any vendors
that can ship or are located near Philadelphia. That
Fish Place in
Lancaster stocks banded cat sharks and they currently have a Wobby
(nothing I have any desire to keep really). The little Orectolobus
they
have is maybe 12 inches long, hopefully it won't end up jammed
into a 55 gallon tank! In any event that is a species that grows far
too large for my keeping.
<Mmm, TFP would be my first choice... they
can order if they're available at the time... as the folks know what
they're doing there, and this would be the shortest (further distance)
for the specimen to travel. Marine Center, Marine Depot can likewise
order/receive/re-ship such an animal to you>
The two species I had
interest in were Atelomycterus marmoratus, and
Atelomycterus macleayi. I have not been able to find them very easily
for sale though. Do you know the basic differences between the
species?
<We've been over this. I encourage you to buy Scott
Michael's excellent work on the captive husbandry of these animals...
and read it thoroughly>
I was leaning towards getting the
marmoratus if possible, but the macleayi is the only species I could
find in the trade.
<Both are offered from time to time... they are
wild-collected... and folks "get around" to them if/when they can...>
The enclosure I have setup for the shark has been running for a while
now and is cycled, currently the tank is empty of fish. The
tank is a 125 with a
sand substrate and that's it. There is no
rock, and a hiding spot would more than likely just end up being a
chunk of large PVC pipe.
<Mmm, I do advise you to make some sort of
larger, heavier structure, with space behind it... to allow your shark
to get out of view...>
I would like to add a large tang to the
tank to go with the shark, but that will come later. I do have a spare
200 gallon tank in the basement, and if need be I will
eventually
set that one up for the shark and any companions (currently I can't
justify such a large tank when the shark I am buying may come to me at
under 10 inches in length!
Do you have any species specific care
advice?
Thanks,
Steve
<A great deal... unfortunately, am
farther behind on other projects... rather than writing about even the
more suitable shark species for aquarium use. Perhaps you would compile
this information, write it up in an article format... I will gladly help
you sell/place it in the e- and paper 'zine mag.s. Bob Fenner>
Re: Coral Catshark 1/19/06
Thanks for the
input. I will contact TFP and see what they can do. I checked online
and found a few books on aquarium shark keeping (one is in stock at
the local book store), and I am going to pick that up as well.

<A good investment. Good luck, life to you. Bob Fenner>
Nurse shark spitting water out of the tank 12/21/05
Ok here
isn't something I have seen before but the shark is doing it most
nights. Once it become night
and he becomes active, he will swim
along the top of the tank. He will then go up to the top of the tank
and spit water. There is one section that is not covered and he send the
water flying out. any reason
for this particular behavior? <First
off Peter, no home aquarium is large enough to keep a nurse shark in
conditions to its liking. Why do pet shops sell these, they need to be
banned. Are you aware these sharks attain lengths of 16 feet? They
will NOT adapt to aquarium conditions and don't listen to anyone who
tells you their growth can be controlled by smaller feedings or by the
size of tank they are in. His behavior is largely due to the negative
conditions he is living in. Stress, my friend. It won't be too long
before he will be attempting to jump out. I'd try to find a home for
him such as a public aquarium. Sharks are best left in the sea where
they will do the most good. James (Salty Dog)>
“Cat” Shark
Care 12/17/05
Hi,
<Hello.>
thanks for all your info
it is very useful...
<Quite welcome.>
I am purchasing a 250
gallon tank to house a baby band cat shark, hope to be an adult cat
shark some day... That is the only fish I plan on having...
<Good sharks should be kept in species only tanks.>
What kind of
filtration system do you recommend?
<A VERY large protein skimmer,
perhaps some type of bio-media (since you won’t be able to keep copious
amounts of Live Rock in the display) or better yet a live
rock/macro-algae refugium and of course LOTS of water flow.>
Is
this size tank big enough?
<It’s hard to say there are a
few sharks labeled with the common name cat-shark (Including
Atelomycterus marmoratus and Chiloscyllium punctatum, the first stays
under 30” while the second grows to over 40” – big difference), and
while the volume of the tank (250-gallons) sounds good on paper, it
would help to know the exact dimensions of the tank. Surface area is
very important with these animals.>
How is the maintenance for this
fish?
<Sharks are not for casual aquarists, be sure to research the
needs thoroughly, re: disease, diet and so on., read the FAQ’s here on
WWM and check out Scott Michael’s, “Sharks and Rays.”>
Thanks for
your help... I have also donated to Amazon Honor System...
<Thank
you for this, Adam J.>
Black Tip Sharks 11/22/05
Hello
<Hey, Mike G here.>
Hope you can help me.
<So do I. :)>
I am after purchasing 2 black tip sharks for an aquarium tank.
<Hope
it is a very, very large aquarium.>
Where would I go about finding
them,
<Not sure... not exactly a readily available species (which is
a good thing, for the most part)
and have you got a estimated cost?
<No, sorry. I'd guess somewhere around $400-$500 for a decent sized one,
but I've yet to see them offered for sale, so...>

Shark
Selection 11/9/05
Dear Mr. Fenner,
<Maria>
We are
Polish company which is doing marine aquariums for private people as
well as other institutions in our country. We also plan to open
Oceanarium in Gdansk.
<How nice!>
We consider you as an expert and
we appreciate you for your knowledge about sharks and therefore I would
to kindly request you for your opinion and help.
<Okay>
One of our
customers asked us to order for him a Blacktip shark to be settled in a
tank with capacity 6000 l. Our knowledge is not sufficient to decide
wither it is big enough to prevent it from hurting itself.
<Mmm,
about 1,600 gallons... should work out only when this fish is small...
for a few years (2,3...), though not for its entire lifetime>
Therefore I would like to kindly ask you for your opinion concerning
this issue. If you consider that it is not big enough that what other
species could be suitable for such a aquarium.
<The Epaulette,
Bamboo and Hornshark families have some suitable species... Please read
here:
http://www.wetwebmedia.com/sharkselfaqs.htm and the linked files
above>
The second thing is, that in the mentioned oceanarium we would
like to create a tank with capacity 40 000l, where we would like to
settle as many different species of sharks as it is possible taking into
consideration their safety of course. We would be grateful for your
suggestion and list of sharks that in your opinion could safely inhabit
one tank.
<Mmm, some species can be mixed... likely you, your
customer/s want more "sharky" sharks... ones that swim about, hover off
the bottom (unlike the families suggested above)... there are some
smaller species here... I would take the time to search through
Fishbase.org, get/use a copy of Scott Michael's shark and ray book...>
<<I also suggest they try to contact the good people at the Long Beach
Aquarium of the Pacific. Marina>>
Thank you in advance. I
am looking forward to hearing from you soon.
Yours faithfully,

Hunting for eels! 11/6/05
Hi, my name is William; I live on an
island in the Caribbean. I live on the shore and lately have been
chasing after what I believe to be chain-link morays.
<Most common
species in shallow water there...>
It seems to be tougher than I
expected. I was wondering if there are anyways of attracting these
magnificent eels to a certain area. Just the other night I went to look
for them since they are nocturnal, but I believe they went out to sea
for feeding. The area I usually find them in is a small cove covered in
spiny lobster, parrotfish, sea urchins, and green morays.
Recently I
have seen three of them in the span of two days. Two of them were large
averaging about one and a half feet long. The third though was quite
skinny and was about eight inches long. Any help would be greatly
appreciated, thank you.
<Can be caught in "minnow traps"
incorporating a fyke on one/both end/s... with bait inside. Or with a
barbless hook and line, with something meaty for bait... or via a small
fence and hand net... Please read here:

Domestic Lantern Shark?!? 8/18/05
Hi
I was Just curious
about a few details in domestic Shark keeping (if that's a word).
Since most Sharks seem to be too large to keep in a normal sized
tank, so I was wondering If I could keep a Lantern Shark as a pet.
If I could, I was wondering if you could tell me a few things about
them, such as temp., diet and tank size.
Thanks
<Have never
seen members of the Family Dalatiidae, Sleeper sharks, kept in
captivity, nor read of others accounts... You still will need to
provide a system of at least three times the adult length and twice
the width of whichever species you'd like to husband. Bob Fenner> |

Domestic Lantern Shark?!? part 2 8/19/05
Are there any other
sharks almost that small?
<See here: http://www.wetwebmedia.com/sharks.htm
Bamboos and Epaulettes are about the best tropical species and horn/port
Jacksons are about the best temperate species. As Bob stated, systems
of at least a few hundred gallons are still necessary with indoor
"ponds" working best. See here:
